Original application filed October 26, 1912, Serial No. 727,919. Renewed January 15, 1918; Serial No. 72,369; Divided and this application filed August 16, 1918. Serial No. 115,149.

To all whom it may concern:

Be it known that I, VVILLIAM E. FIOKLEN, of College Point, in the county of Queens. and in the State of New York, have invented a certain new and useful Improvement in Edge-Protectors for Artificial Stone, and do hereby declare that the following a full, clear, and exact. description thereof.

My invention relates to metal nosings, or edgings. for artificial stone and is a division of rny copending application filed October 9.6, 1912, Serial No. 727.919. renewed January 15, 2916. Serial. No. 72,369, now Patent No. 1,201,052. granted October 17, 1916. More l.l.l,l "lll:ll'l 'v' the invention is adapted as an edging for curbs, gutters and other structures, the edges of which are curs-"ed or rounded longitudinally. Tn curbs and gutters, such cn'rvcs occur at street corners, and may Occur at other points, if the streets 01 roads are not straight. Metal edge-protectors of the general character of the present invention are positioned 'in the concrete or other material forming the artificial stones or blocks, before the material has set; and, according to the shapev of the metal, are more or less securely anchored in the material by the setting or hardening of the latter. For many uses. as for instance when used as a curb or gutter edge, the metal must' be of substantial size and strength; and, to have the requisite rigidity and depth of ail-v chorage, is usually provided with a web .01 ribywhich lies in a plane transverse to the direction in which the edge extends.

A favorite type of. edge protectors has the general shape at a T iron, the crossin'ember of which is ihe'wearing member, and the upright oi whichis the anchoring member.

As shown in the at-coinpanying drawings, the wcarii' g ine mbcrtis of heavy bull nose con'Ft'H'iilatiUlL This form of protector, although admirable so far as its wearing qualities are concerned, is 'dillicnlt to bend to the shape of corners and other curvesf Inmany instances it is impossible to bend the protector, cold, and at the place of use; and great delay and expense are involved in 0rdcriug especially shapcd sections from the shops. Obviously, special shapes cannot be kept in stock in any suflicient amonnt, to meet, demands. The dillioulty in bonding is obviously due to the position of the rigid central web, and to the lines on which it must be bent in following the street corners and curves. Some forms of T'bztrs are provided with 1111 spacious openings or cuts at considerable intervals to serve as elements to interlock the concrete with the protector. Where such openings or cats exist, the bar can be bent, but the d ifiic'ul't-y of bending the bar to the true curve is nevertheless increased, because the bar will always bend at the weakest point, and so bends out at the cuts or openings. A bar bent in this lat.- ter manner is not only humped and unsightly, but is weak at thecurves, where, to receive the impact of heavy trucking and the like, it should be strongest The purpose of the present invention is to render the anchoring web pliable so that it can be shaped to any cur-ve,-wh-ile cold, and at the place where it is to he used; without, however, involving a shortening-of the web, or otherwise mat eria-llyweakening the web, or lessening the depth of anchorage, and also to anchor the web securely in the concrete. -This purpose is effected in the present, invention by perforating the Web with numerous closely arranged small openings or by cuts of vari ms -l(in(l s-.: In addition to the erforati-ons, it. is desirable to form anchoring toi-igucs on iEorcecl. -nlt poi-*- tion's l) on the bar. The 'p" fomtizons ot course, by reason of the eomgretewhioliqpnlets the same. will in themselves, tow-greater or less extent, assist in anc'li'or'ingfthebar;

and, according tothe nil-ti; 'f-th glo-meratc, should be consit ed in-t motion, The holes lying elose. fitogtgthou, is.

permit bending of the web, later and vertically; so that, at. -theyonrveo distal edges of the. w ehay'bercritirpi "and the web turned slight] fro its posit]. f

perpendicnlarity to the weaninglow for the d-illcreneei n length-oi?" the outer and inner .iporlti-ons ofthq-bar atsnch points.

An important 'lea'ture wit theinvention concerns the manner in which the-protector and concrete are-"bound, toga r. 'Hflhctol'oro, the anrhori-ngoffithe aa l heen -ef fP-(i ed either by p'roic(-'-tions "from-l he baig-pr by holes in the bar, spaced a-tconsitlemtble intervals apart. When suchr-a. bar.-i s.siihjectod to heavy blows, it, will work :lfimte from the chora ge,

concrete between thejpoi'ntsiof nth and presently will have a slight an 5 8 to "n l-:1

play or spring, so that thereafter each blowon the bar will (alle e the. bar to act; as: a wedge tending to split the eonerete. in many instances the eonerete will ultimately split entirely away on one side of the bar. In the present invei'ition hoot-\er by irannn ol' the large number of small anchoring points provided hr the innnerona perforations or nuts. or by I'IIIHIII of a part i) loreed down from the web ,to train anchoring porlions, there can he l1(i l;.lllii; f point l'or illl i looseness ol' the lmr.
